WebØ RC4 – this algorithm is used to create pseudo-random stream of bits (a key-stream). As with any stream cipher, keystreams can be used for encryption Ø A stream cipher is a symmetric key cipher where plaintext digits one at a time are XORed with corresponding digits of pseudorandom stream of bits (keystream) to create encrypted message i.e. … WebIntroduction to SHA. SHA stands for secure hashing algorithm. SHA is a modified version of MD5 and used for hashing data and certificates. A hashing algorithm shortens the input data into a smaller form that cannot be understood by using bitwise operations, modular additions, and compression functions. You may be wondering, can hashing be ...

In cryptography, RC4 (Rivest Cipher 4, also known as ARC4 or ARCFOUR, meaning Alleged RC4, see below) is a stream cipher. While it is remarkable for its simplicity and speed in software, multiple vulnerabilities have been discovered in RC4, rendering it insecure. It is especially vulnerable when the beginning of the output keystream is not discarded, or when nonrandom or related keys are used. Particularly problematic uses of RC4 have led to very insecure protocols su… greenwich bexley hospice shop
